With the improvement of living standards, our interest in good indoor air quality has increased significantly.
Flexible duct are particularly important for the improvement of indoor air. Wet and dark duct system is an ideal place for mold breeding. In addition, there are fungi, bacteria and other microorganisms. People’s exposure to indoor air through breathing can lead to respiratory problems, infectious diseases or other allergic reactions and various human health effects. Therefore, it is meaningful to use antibacterial pipe materials to prevent mold growth.
1. Natural silver antibacterial agent
As a natural antibacterial agent, silver has a long history in the field of human health care. According to many scientific experiments, silver particles are effective against more than 600 microorganisms. The main components of antibacterial agents of silver materials are silver ions and zeolite, which are used as carriers of silver ions and release them. When water is present, zeolite can act as an ion pump and release silver ions into the environment. Antibacterial coating can inhibit the growth of bacteria, fungi, molds and other microorganisms by releasing silver ions. Through the controllable release of silver ions, the equipment can be prevented from being infringed by microorganisms.
In the production process of air duct materials, silver ion antibacterial agent is coated on the surface of composite pipes, placed in the inner core of the ventilation duct, and the outer layer of the duct is covered with film for antibacterial, which cannot be achieved by spray, coating or ultraviolet lighting, and will not peel off with the passage of time.
2. Antibacterial effect of copper
Copper ion is a catalyst for the internal oxidation process of cells, which can inhibit bacteria and viruses. In history, copper has a history of 10000 years. It is a natural bacteriostatic agent, fungicide and preservative. It has the characteristics of analgesia, antipyretic, antibacterial and anti-inflammatory. However, copper is also one of the necessary trace elements in the body, so it can be metabolized normally in the body. When the body lacks copper, it will cause anemia, hair, iliac and arterial abnormalities, so as to prevent brain disorders.
Copper is a natural antibacterial material because it self-disinfects surfaces without the need for electricity or bleaching. During the period of industrial life, the amount of copper made the materials used in fixed installations and buildings flourish. In recent years, relevant researchers (have begun to pay more attention to the antibacterial properties of copper and to prevent cross infection of bacteria in hospitals. Research shows that copper ion can kill bacteria by forming holes on the surface of bacteria that can cause “short circuit”.
Copper plastic composite air duct material is composed of internal copper film. Aluminum foil and two layers of polyester film are used as protective layers. It has corrosion resistance, water resistance and compression resistance, and can naturally prevent the diffusion of most pathogens in the air.
This is two common antibacterial materials for flexible duct. You could choose the appropriate antibacterial materials according to the effect, price and scope of application.
